Trine 2 is good. I liked the first one too.
I beat A Link Between Worlds and got diamond Knack on Knack, took 3 and a half playthroughs to get it, now I'm 100% finished with it (although I might run through very hard). I might also play Hero Mode on A Link Between Worlds as it was unlocked once I beat the game.
As for new games, Super Mario 3D World is next. I hear it's right on par with Galaxy 1/2, considering those were two of the best games last gen, I'm excited.
